Move the slime with the mouse. The slime can only touch dots that are the same color as it. The slime will change color when it eats a dot. Once your slime is big enough, it will be sent off, and you will get a new one. If the slime touches a dot that is not its color, it will shrink back to its original size. The dots fall slightly faster the more slimes you make.
